RE: More power (literally) for the HP-41, follow-up.
Just finished a marathon test with Diego's 82120D (Beta).
Setup: HP41CL with TIME module and the PPC rom plugged. Running PNG (Prime Number Generator) from the PPC manual examples, slightly modified to print the prime with the time indication and testing flag 49 for battery status, print this when BAT is low. Printing using the YPRT ROM to print into the serial port with a PC connected, printing to the HP82240 simulator in HP82143 mode. Running in TURBO 50 mode all the time with the serial port active. Running time until BAT appearance: 59 hrs 23 minutes Running time from BAT until OFF: 12 hrs 28 minutes Total running time 71 hrs 51 minutes, highest prime found is 455921 Compared with my own built 1100 mAh battery solution: total running time 36 hrs 35 minutes (no BAT indication) Compliments to Diego for another fine HP41 necessity! Here is the program used: Code: 01◆LBL "PNG" Regards, Meindert |
